Given Input Data is 909, 135, 406, 855

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 909 is 3 x 3 x 101

Prime Factorization of 135 is 3 x 3 x 3 x 5

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 855 is 3 x 3 x 5 x 19

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(909, 135) = 13635

GCD(909, 135) = ( 909 x 135 ) / 13635

GCD(909, 135) = 122715 / 13635

GCD(909, 135) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 406

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(9, 406) = 3654

GCD(9, 406) = ( 9 x 406 ) / 3654

GCD(9, 406) = 3654 / 3654

GCD(9, 406) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 855

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

GCD(1, 855) = 855 / 855

GCD(1, 855) = 1

GCD of 909, 135, 406, 855 is 1
